This sometimes happens if a print job freezes before, or during the print. I would suggest two things. Open up your print que, which you should be able to access from the bottom right hand side of your screen in your task bar. Right click, and open print que. If there is a print job in the que that says printing, try to right click on the job and cancel it. If this does not work and you have not done so already, restart your computer and your printer! Go back into the que if you have to and if the job is still there, right click and cancel job again. Then, retry printing a something different from your printer. This should solve your problem.

This is usually caused by data within the print job. Microsoft Office sends paper size and job data with each job. Clear all print jobs in the computer sending the job.(Start/Printers/double click the canon printer and delete all jobs in the print que. Clear the Canon by off/on. Open a program and print a standard letter size document to test. This can be corrected by going to the page/document setup choices under "File" or the Ball in MS Office. Usually this is set to A4 or Bypass by mistake within the application.Thanks

Yes, printer won't print if print queue is full. The fact is you are lucky your printer is giving you this message. Most printers, when queue is full, will just remain silent and leave you wandering what in the world has gone wrong.Solution is to clear the print queue. See, when you send to print and you send another when the previous hasn't printed, they queue up. Now if for any reason the first fails to print, all others will just remain queued up but will not print until you clear the print jobs queued up.To do, this go to start/control panel/printers. Right click on printer icon and select open. The respective print queue box appears. It should have all of the print jobs listed there in the box. On the menu bar click on printer and select "Cancel all documents." A box appears asking you to confirm if you want to cancel, answer yes. Then try to print again. If it still fails to print restart your PC and try to print again.

It seems the printer buffer memory has overflowed. Cancel the print from the print Que and switch off the printer. Give your PC a reboot too. Now switch on the printer and make sure that there is no document in the print Que. If its still there, disconnect the printer and delete the pending job, i.e. print Que. After the printer shows it ready for printing do not release the entire document for printing at one go. Breakup the print job in 3 parts and for each part manually enter the page numbers and then give the print command. Repeat this till the entire lot is over..........................sodeep

Have you tried unpluging your printer from the computer as well as unpluging the printer from the electrical? If that doesn't work you should start from scratch... that is remove the printer from the computer memory, delete it, turn off the computer, turn on the computer and go through the installation process as if you just purchased the printer. Barring any mechanical problems as in jams or the such, the printer should return to operational status.
